Although in the recent past arch-rivalry between, SRK and Salman, seems to be mellowing on personal front, but if we talk about their BO battle then it's is something everlasting.
Interestingly, much before her Bollywood debut opposite SRK with "Om Shaanti Om", post which Deepika turned in to a SRK loyalist of a sort, she was offered with an opportunity opposite Salman, but because of her not being prepared for camera she declined the offer.
But now with some remarkable figures on her performance report-card, and some good offers in her kitty, Deepika seems to be quite eager to take a quantum leap by working with "Sultan of BO", Salman.
Whatever, all we can say about this is that probably, with his equations getting better with every passing day may be, Deepika's mentor SRK too will not mind her sharing screen space with Salman in future.
